This lever is located Within the housing '23 and is secured to the end. of the rock-shaft 41 which is moved bythe arm 40 through suitable rods and levers (not shown) to shift the gear wheels 31 and33, whereby the gear wheels 25,31 and 33 may be disconnected,

the gear -Wheel31 engaged with the internal 25, or the gear wheels 25 and 31 intermeshed respectively with the teeth 34 and 35 of the gear wheel floating support C is substituted for the ordinary distance devices and torsion of two I beams 42 joined in diverging rela- "tion to each other by the link:-43.- The rear end of each beam 42 is provided with a yoke H44 and said yoke is connected by a pin 45 with one of the lugs 13 on the axle 12'. The

braces for the-rear axle 12 and constitutes a base for the motor.- This support consists end :with a ball 48. The bracket 49, cen-- trally arranged on the beam 11', is provided --With a ball socket 50 to receive the'ball 481 and said ball is movably retained in said illustrated, however, is an: electric motor connected with a suitable source ofpower and controlled by mechanism not'shown.

- Itwill'be noted that the floating unitary structure formed by rigidly connecting the motor, transmission, axle and support C prevents the vibration and distortion ofthe driving mechanism and thereby prolongs the life of the vehicle, rendering the'same'more efficient and minimizing the attention nec'eS sary in operating the same. i 1 V I that the force, caused It will also be noted by the end thrust of the worm, which tends to turn the vehicle advances, is substantially counthe axle 12 and lift the support when 3 worm shaft is revoluble,

being rigidly shafts to turn the same at preventing shocks to the frame, when the quickly started, and eliminating vehicle is long strains upon the connection between the support C and the frame 10.

' aving described my invention, what I claim as new and desire to protect by Letters Patent, is:

1. In a self-propelled vehicle, an axle havg driving shafts therein and differential gearing connecting the same, traction wheels on said shafts, a frame supported on the axle, a floating support between said frame and axle, a worm in mesh with said differential gearing, and a motor connected with said Worm for turning the same, said motor secured to the axle and attached' to said floating support between its ends to hold the axle against rotation and distribute the rotative force thereof between the frame and axle.

2. In a self-propelled vehicle, a driving mechanism including a motor provided with a casing, a transmission housing rigidly secured to said casing, an axle rigidly secured to said housing and containing driving shafts and differential gearing therefor,v a worm shaft revolubly mounted within said axle and furnished with a worm gear in mesh with said differential gearing, said shaft being in alinement with the motor shaft and protruding into the housing, a bearing within said housing in which said within said housing for connecting the and for disconnecting said shafts.

3. In a self-propelled vehicle, a driving mechanism including a motor provided with a casing, a transmission housing'rigidly seof said driving gear,

and means also variable speeds cured to said casing, an axle rigidly secured to said housing and containing driving shafts and differential gearing therefor, a worm shaftrevolubly mounted within said axle and furnished with a worm gear in mesh with said differential gearing, said shaft being in alinement with the motor shaft and protruding into the housing, a driving gear on the motor shaft, a bearing for said worm shaft supported at the center a driven gear slidable on the worm shaft and means for engaging and disengaging said driving and driven gears.

4. In a self-propelled vehicle, a frame, a driving mechanism including a motor provided with a casing, a transmission housing rigidly secured to said casing, an axle rigidly secured to said housing and containing driving shafts and differential gearing therefor, a worm shaft revolubly mounted within said axle and furnished with a worm gear in mesh with said differential gearing, said shaft being in alinement with the motor shaft and protruding into the housing,

a bearing within said housing in which said worm shaft is revoluble, means also Within said housing for connecting the shafts to turn the same at variable speeds and for disconnecting said shafts and a floating support between said axle and frame upon which said motor is mounted.

In testimony whereof, I have signed my name to this specification in the presence of two subscribing witnesses.
